Installed 2.0.1 and get the message "It seems to be script is not installed." when calling index.php.
The admin panel starts well but gives the same message when calling any module like the Karma or the CAPTCHA module. The Error Log is empty. The install instructions were followed exactly, all checks gave OK responses before, during and after install.
It's not mentioned in the message what script is not installed. What could that be??
I even uninstalled all modules and widgets, troubleshooter says all ok - problem remains.
